AC ETYLEN E-GAS LAM P.

SPECIFICATION: forming part of Letters Iatent No. 650,854, dated June 5,1900. Application filed January 13, 19Q0. Serial No. 1,262. (No model.)

To aZZ whom it 17mg concern:

Be it known that I, ARTHUR K. MILLER, a citizen of the United States,residing at Waterbury, county of New Haven, State of Connecticut, haveinvented certain new and useful Improvements in Acetylene-Gas Lamps, ofwhich the following is a specification.

One object of my invention is to provide improved means for feedingwater to calcic carbid, to the end that the feeding of water can beconveniently regulated in accordance with the quantity of gas to beevolved.

Another object of the invention is to provide an improved constructionof acetylenegas lamp particularly adapted for useon vehicles.

The invention also consists in the novel de-' tails of improvementthat'will be more fully hereinafter set forth and then pointed out inthe claims.

Reference is to be had to the accompanying drawings, forming parthereof, wherein Figure 1 is a plan view of a lamp embodying myimprovements, the cover being removed. Fig. 2 is a partly-sectional sideelevation thereof, and Fig. 3 is a vertical cross section on the planeof the line 3 3 in Fig. 2.

In the accompanying drawings, in which similar numerals of referenceindicate corresponding parts in the several views,'1 indicatesalamp-body, which is shown provided with three main compartments 2 3 4.In the arrangement shown these compartments are formed by means of ahorizontally-disposed partition 5, secured to the walls of the body, anda vertically-disposed partition 6, from which a top wall 7 extends'toand is connected with the walls of the body l, (see Figs. 1 and 2,) andthus the body and partitions 5 6 form the chamber 2, the body, with thepars. titions 5 6 andwall 7, form-the chamber 3, and the body andpartition 5 form the chamber 4 beneath the chambers 2 and 3. The chamber2 contains a burner 8, that communicates with chamber 4, and thuschamber 2 constitutes a fire-chamber. The chamber 3 constitutes awater-chamber and the chamber 4 a gas-generating chamber. The wall 7 isshown provided with a screw-cap 9 for the admission of water;

10 is a perforated cover or cap on body 1, that forms the cover ofchamber 2.

The front wall of chamber 2 has an opening protected by a glass or othersuitable protector 11, which in Fig. 1 is shown curved to correspond tothe curve of body 1 and lies against the inner surface of the frontwallof chamber 2, and 12 is a reflector, which extends across chamber 2 atthe back part of the same behind burner 8 and has its ends bent orcurved forwardly, so as to engage the adjacent vertical edges ofprotector 11, and the reflector 12 preferably has a central de pression12", which may be oval, that bears against the partition 6, and thus theparts 11 and 12 are braced against each other and held firmly withinchamber 2. The parts 11 and 12 are inserted in chamber 2 by sliding themin through the top opening when the cover or cap 10 i'sremoved and theyare held down by the cover or cap. V

13 is a conduit located within the waterchamber 3 and having one 'endleading through an opening in the bottom partition 5 thereof and itsother end opening through the outer wall of said chamber. (See Fig. 3.)This conduit is provided with a valve '14, shown in the form of a screwor threaded stem meshing in threads in the conduit and having a taperingend 14 to'fit against a seat in conduit 13, an enlarged portion 13 ofsaid conduit being in line with a rednced'portion' of the valve-stem, anaperture 13 in the'wall of the conduit permitting water to pass fromchamber 3 into the conduit. The valve 14 is shown provided with a head14 for operating it, and packing 15 serves to make a tight joint. Theinner end of the conduit 13 leads to a hollow hanger or support 16, thatis secured to the partition 5 and depends there- 0 from into chamber 4,said hanger being provided with internal screw-threads thatreceivecorresponding threads on a depending tube 17. Said hanger is shownprovided with a shoulder 16, against which a cup or the like 18 rests,the upper edges-of'said cup resting againstthe partition 5,and thusforming a chamber to contain a suitable gas-filter, one or moreapertures 18 in the cup 18 permitting gas to enter the'same. The burner'100 8 leads to the chamber formed by the cup 18 and the partition 5.(See Fig. 2.) The hanger 16 also has external threads that mesh withinternal threads at the upper end of a chamber 19, that has a closedlower end, the tube 17 projecting into said chamber to a point above thelower end of the latter, thereby forming a water-receptacle or well 20between the lower ends of said parts. (See Fig. 3.) The chamber 19 isshown screwed against the bottom of cup 18, and thus, in con junctionwith the support 16, holds the latter pressed against the partition 5.21 is an absorbent material, such as a fibrous wick, surrounding tube 17and located within chamber 19, the lower end of the wicking leading tothe water-receptacle or well 20 but not to the bottom of chamber 19. Thechamber 19 near its upper end is provided with one or more ports 20 forthe escape of water.

\Vhen the valve 14 is opened, water passes through conduit 15 and tube17 into the receptacle or well 20 in chamber 19 and engages the wick 21,and is drawn up through the latter by capillary action, escapes throughthe port 20, and trickles down the exterior of chamber 19. Theconstruction is such as to provide a uniform water feed, or one'that isnot affected either by changing weight of water above the feed-tube orthe pressure of gas at the outlet, and an alternating pressure betweenthe gas and water is prevented. Thus the small well of water is at thelower part of the lamp,while the reservoir is above, and the feedingaction of the water is by capillary attraction upwardly through the wickto the port 16, discharging above the carbid. Chamber 19 projects incalcic carbid to deliver water thereto. The chamber 19 is shownprojecting through an aperture in the cover 22 of a carbid-receptacle23, that is located within the lower end of chamber 4:, and held inplace by a cap it, attached to body 1 by any suitable means, such as apin and slot 25 26, whereby the cap can be removed. To make a gas-tightfit, the receptacle 23 is shown provided with a flange 23, that isalined with the end of body 1, between which a gasket 25 is located, andthe end of body 1 is shown bent inwardly to form a somewhat broad seatfor the gasket to rest against.

I do not limit my invention to the details of construction shown anddescribed, as they may be varied without departing from the spiritthereof.
